Comparison: DEMSA2 L1 vs L2

Demsa2 L1vsl2

What is the difference between our DEMSA2 L1 and L2 products?

Both are a digital surface model (DSM), but L1 is a raw version straight off our assembly line and can include some artefacts resulting from our photogrammetric extraction process. The most common artefacts occur over water bodies such as rivers and lakes, but other instances also include large power lines, solar plants, and in rare cases, orchards and row crops.

In our L2 product, extensive quality control is conducted to identify and fix these artefacts as best as possible.
